The large-scale livestock and poultry organic fertilizer production line with an annual output of 100,000 tons includes: forklift feeder, trough turner, vertical pulverizer, drum screening machine, dynamic batching machine, granulator, round throwing machine, dryer, Cooling machine, coating machine, automatic quantitative packaging scale. Users can customize the appropriate configuration according to their needs.
And each kind of production line has its own characteristics, what kind of organic fertilizer is suitable for making what kind of organic fertilizer equipment is needed, such as the production line of disc and rotating stock stirring tooth must be equipped with drying and cooling machine, and the organic fertilizer Drying, and then use the cold air ventilation system to cool down the organic fertilizer, so that the hardness of the granules will be better.
The granulation disc angle of the disc granulator adopts an overall arc structure, and the granulation rate can reach more than 93%. The granulation disc is equipped with three outlets, which is convenient for intermittent production operations. The reducer and the motor are driven by flexible belts, which can start smoothly, reduce the impact force, and improve the service life of the equipment. The bottom of the granulation tray is reinforced with multiple radiant steel plates, which is durable and never deformed. Heavy, thickened, and solid base design, no need for anchor bolts, stable operation. The main gear of the granulator adopts high-frequency quenching, and the service life is doubled. The granulated face plate is lined with high-strength glass fiber reinforced plastics, which are anti-corrosion and durable.
Production process of large-scale livestock and poultry organic fertilizer production line with an annual output of 100,000 tons:
1. For piles of ground strips, use a ground turning machine, or put materials in the fermentation tank, use a trough turning machine.
2. Sprinkle organic fertilizer starter evenly, turn over and ferment to heat up, eliminate odor, decompose, and kill miscellaneous fungi and grass seeds.
3. Fermentation for 7-12 days, depending on the temperature of each place, the number of turning times varies.
4. Fully fermented and decomposed, out of the pool (ground type is directly piled up with a forklift).
5. Use a grading sieve to carry out coarse and fine screening (the screened powdery fertilizer can be sold directly).
6. The screened large pieces are crushed with a pulverizer and then returned to the classifying sieve.
7. Mix the required trace elements with a pre-mixer.
8. Granulate with a granulator.
9. Send it to the livestock and poultry organic fertilizer dryer and cooler.
10. Transport to the automatic packaging machine for finished product packaging and sale.
Precautions for fermentation of large-scale livestock and poultry organic fertilizer production line with an annual output of 100,000 tons and common problems of organic fertilizer fermentation:
Slow temperature rise: the pile does not heat up or heats up slowly.
Possible reasons and solutions:
1. The raw materials are too wet: add dry materials according to the ratio of materials and then stir and ferment.
2. The raw material is too dry: according to the humidity, add water or wet materials to keep the moisture at 45%-55%.
3. Insufficient nitrogen source: Add ammonium sulfate with high nitrogen content to maintain the carbon-nitrogen ratio at 20:1.
4. The pile is too small or the weather is too cold: pile up the pile high and add easily degradable materials such as corn stalks.
5. The pH is too low: when the pH value is less than 5.5, lime or wood ash can be added and stirred evenly to adjust the pH of the fermentation pile.
Heap temperature is too high: Heap temperature ≥ 65°C during fermentation.
Possible reasons and solutions:
1. Poor air permeability: Turn the pile regularly to increase the air permeability of the fermentation pile.
2. The pile is too large: reduce the size of the pile.
Odor: There is a constant smell of rotten eggs or decay coming from the pile.
Possible reasons and solutions:
1. The content of ammonia is too high (C/N is less than 20): Use deodorant for disinfection and deodorization, and add substances with high carbon content such as: crop straw, peanut husk, rice husk, etc.
2. The pH value is too high: add acidic substances (calcium phosphate) to lower the pH value, and avoid the use of alkaline ingredients (lime).
3. Uneven ventilation or poor airflow: remix the material and change the formula.
4. The material stacking is too dense: re-mix the stack, and add large-grained materials as appropriate according to the material density.
5. Anaerobic environment: Turn the pile regularly to increase the oxygen content in the pile.
Mosquito breeding: There are mosquito breeding in the fermentation pile.
Possible reasons and solutions:
1. Raw materials are stacked for too long before fermentation: quickly process raw materials, spray probiotic deodorant on the surface to reduce odor and mosquitoes.
2. Fresh feces cover the surface of the heap to breed mosquitoes and flies: turn the heap every 4-7 days, and cover the surface of the static heap with a 6cm compost layer.
Material agglomeration: There are large parts of the fermentation material in the pile, and the structure is inconsistent.
Possible reasons and solutions:
1. Inhomogeneous mixing of raw materials or insufficient turning: improve the initial mixing method.
2. Uneven airflow or insufficient surround: Sorting or crushing compost to improve air distribution.
3. Raw materials contain bulky and non-degradable or very slow-degradable materials: sorting compost, crushing, and sorting raw materials.
4. The composting process is not over: extend the fermentation time or improve the fermentation conditions.
